Hey Steve, when you look at the schematic you can see, that it is only for protection against negative voltage / spikes. I have seen many that were burned. Two reasons for that: somebody was too stupid to install the battery correctly or it is a Zener-Diode and protects it against over voltage. Well - then it would protect the whole car against that, but the size of the diode doesn't allow it to be a real safety device... To make it short - even if you leave it out you won't sense a difference. It ha snothing to do with the regular function of the module ! Use a 1N4002 or similar if you want to replace it, but don't spend too much time on it. A good idea is to replace the relays, and/or do my modification as described on the DMCNEWS and - to really protect it from burning the solenoids - install a circuit breaker (7...10Amps) in the thick red wire. But one that needs to be reset manually !!! (costs around $5) Elvis & 6548 - 30kmiles/6 years on the same door lock module without any problems ! Of course with remote door lock and opener... > Does anyone know a part number (Radio Shack or equiv) for diode D4 of the lock module? > Mine is dusty grey in appearance and I have had some rare loss of function.
